Parameters
addressPointer to buffer where to write IPv6 address string. Must have space at least for 39 characters and NUL terminator.
Returns
MESH_ERROR_NONE on success.

Function gets RADIUS shared secret from Border Router.

Parameters
shared_secret_lenOn function call, is the size of the shared secret write buffer in bytes, on return is the shared secret length in bytes.
shared_secretPointer to buffer where to write shared secret or NULL. At maximum, bytes set by the length parameter are written. If NULL only buffer length is returned.
Returns

mesh_error_t get_rpl_parameters ( uint8_t *  dio_interval_min,
uint8_t *  dio_interval_doublings,
uint8_t *  dio_redundancy_constant 
)

Get Wi-SUN RPL DIO trickle parameters.

Function reads DIO trickle timer Imin, DIO trickle timer Imax and DIO trickle timer redundancy constant from Border Router. Mesh interface must be initialized before calling this function.

Parameters
dio_interval_minDIO trickle timer Imin parameter.
dio_interval_doublingsDIO trickle timer Imax parameter as doublings of Imin.
dio_redundancy_constantDIO trickle timer redundancy constant.
Returns
MESH_ERROR_NONE on success.
MESH_ERROR_UNKNOWN in case of failure.
mesh_error_t info_get ( ws_br_info_t info_ptr)

Get Wi-SUN Border Router information.

Function reads RPL information from Border Router. Mesh interface must be initialized before calling this function.

Parameters
info_ptrStructure given to stack where information will be stored
Returns
MESH_ERROR_NONE on success.
MESH_ERROR_UNKNOWN in case of failure.
int routing_table_get ( ws_br_route_info_t table_ptr,
uint16_t  table_len 
)

Get Wi-SUN neighbor table information.

Function reads Routing Table information from Border Router. Table is Parent child relation using the Global address IID of the devices. To get the full IPv6 address of the device, IPv6 = Global Prefix + IID. Mesh interface must be initialized before calling this function.

Parameters
table_ptrApplication allocated memory block where routing table is written.
table_lenLength of the table allocated by application given as amount of entries.
Returns
0 - x on success indicates number of entries written to the table_ptr.
<0 in case of errors.
mesh_error_t set_dns_query_result ( SocketAddress address,
char *  domain_name 
)

Set DNS query result to Nanostack cache.

Function sets DNS query result to Nanostack cache to get distributed to the devices in the Wi-SUN network. Function must be called for a running Wi-SUN Border Router instance.

Parameters
addressresolved address of domain_name.
domain_namename of the domain. Must be non-NULL.
Returns
MESH_ERROR_NONE on success.
error value in case of failure.
mesh_error_t set_pan_configuration ( uint16_t  pan_id)

Set Wi-SUN PAN configuration parameters.

Function stores new parameters to Border Router and uses them when mesh interface connect() is called next time. If device is already connected to the Wi-SUN network then device will restart Wi-SUN network after changing the PAN configuration parameters. Mesh interface must be initialized before calling this function.

Parameters
pan_idPAN ID. 0xffff will generate the PAN ID on the mesh interface connect() call if not already generated.
Returns
MESH_ERROR_NONE on success.
MESH_ERROR_UNKNOWN in case of failure.
mesh_error_t set_radius_server_ipv6_address ( const char *  address)

Set Wi-SUN RADIUS server IPv6 address.

Function sets external RADIUS server IPv6 address to Border Router. Setting the address enables external RADIUS server interface on Border Router. To disable external RADIUS server interface, call the function with address set to NULL. The RADIUS shared secret must be set before address is set using set_radius_shared_secret() call.

Parameters
addressPointer to IPv6 address string or NULL to disable RADIUS. Address string format is e.g. 2001:1234::1 and it is NUL terminated.
Returns
MESH_ERROR_NONE on success.
MESH_ERROR_UNKNOWN in case of failure.
mesh_error_t set_radius_shared_secret ( uint16_t  shared_secret_len,
const uint8_t *  shared_secret 
)

Set Wi-SUN RADIUS shared secret.

Function sets RADIUS shared secret to Border Router. Shared secret may be an ASCII string. Check the format and length constraints for the shared secret from the documentation of RADIUS server you are connecting to.

Parameters
shared_secret_lenThe length of the shared secret in bytes.
shared_secretPointer to shared secret. Can be 8-bit ASCII string or byte array. Is not NUL terminated.
Returns
MESH_ERROR_NONE on success.
error value in case of failure.
